Elizabeth even reveals the one thing that made it so special. Nope, not Kristen’s dress — you’ll never guess!

If you thought Kim Kardashian and Kate Middleton‘s weddings were the ones to top, think again. HollywoodLife.com spoke with Twilight actress Elizabeth Reaser at a special screening of the new TIME/HBO documentary Beyond 9/11 on Sept. 8 and she couldn’t stop raving about Robert Pattinson and Kristen Stewart‘s onscreen nuptials. The gorgeous brunette even revealed the unlikely reason that made it so perfect!

“It’s just the most beautiful wedding I’ve ever been to,” Elizabeth told us at the opening of Marco Grob’s TIME Portrait Series exhibition. “And I don’t want to diss all of the other weddings that I’ve been to in my life.”

But what made it so perfect? Believe it or not, Mother Nature!

“It was so beautiful and rain makes things look beautiful,” she said. “The light was stunning and the flowers I mean — there are certain things I can’t say … I can’t say anything more.”

There you have it HollywoodLifers, now get excited for Nov. 18 when it hits theaters!
